SWEep:SPACing {LINear|LOGarithmic}
SWEep:SPACing?
Select linear or logarithmic spacing for the sweep. The default is Linear.
The :SPAC? query returns “LIN” or “LOG”.
•
For a
linear
sweep, the function generator varies the output frequency
in a linear fashion during the sweep.
•For a logarithmic sweep, the function generator varies the output
frequency in a logarithmic fashion during the sweep.
SWEep:TIME {<seconds>|MINimum|MAXimum}
SWEep:TIME? [MINimum|MAXimum]
Set the number of seconds required to sweep from the start frequency
to the stop frequency. Select from 1 ms to 500 seconds. The default is
1 second. MIN = 1 ms. MAX = 500 seconds. The :TIME? query returns
the sweep time in seconds.
•
The number of discrete frequency points in the sweep is automatically
calculated by the function generator and is based on the sweep time
that you select.
SWEep:STATe {OFF|ON}
SWEep:STATe?
Disable or enable the sweep mode. To avoid multiple waveform changes,
you can enable the sweep mode after you have set up the other sweep
parameters. The default is OFF. The :STAT? query returns “0” (OFF) or
“1” (ON).
• The function generator will not allow the sweep mode to be enabled
at the same time that burst or any modulation mode is enabled.
When you enable sweep, the burst or modulation mode is turned off.
